AUTOGRIP® CB/CB-A Pull Back Collet Chuck - Mainly on NC turning Machines, Special Purpose Machines

Draw Back Collet Chuck

Draw Back type

DRAW BACK type collet chuck used mainly on CNC turning machines, special purpose machines, etc.
Suitable for machining bar material and mandrel.
High clamping accuracy, high speed and high rigidity.
The installation is the same as “Thru-hole power chuck” and they are replaceable with each other.
This is a completely sealed design, which prevents coolant and chips from entering the spindle.
J is the hole diameter of blank draw nut, K is the maximum thread specification, and it could be customized.
